Description

Adopt the HSDPA scheduler and the dispatching method of MU MIMO technology

Technical field

The present invention relates to the mobile communication technology field, particularly high-speed downstream bag (HSDPA) access technology relates in particular to a kind of HSDPA scheduler and dispatching method that adopts multi-user's multiple-input and multiple-output (MU MIMO) technology.

Background technology

At present, in high-speed downstream bag access (HSDPA), introduced multi-user (MU) multiple-input and multiple-output (MIMO) technology.That is: at down direction, a plurality of HSDPA subscriber equipmenies (UE) can be shared identical scheduling high-speed Physical Downlink Shared Channel (HS-PDSCH) resource.For these UE that shares identical scheduling HS-PDSCH resource, distribute different training sequence deviation for these UE based on the configuration mode of special default training sequence deviation (Midamble Shift).These different training sequence deviation are used for distinguishing the wireless channel of these UE.

Particularly, in the HSDPA that adopts MU MIMO technology, with K in the sub-district _mIndividual training sequence deviation is divided into the M group and shares identical scheduling HS-PDSCH resource in order to support M HSDPA UE in MU MIMO mode.The group number of M group training sequence deviation is respectively 0,1 ..., M-1.Work as K _m=2 o'clock, M=2; Work as K _m∈ 4,6,8,10,12,14, and during 16}, M=2,4.K _mHave with the value combination of M: the 1+7*2=15 kind.

For every kind of K _mValue combination with M, m ∈ { 0 in the M group training sequence deviation, 1, ..., each training sequence deviation that comprises in the M-1} group training sequence deviation and the mapping relations between Orthogonal Variable Spreading Factor OVSF (OVSF) channel code are defined with special default training sequence deviation configuration mode in the 3GPP agreement.This mode is represented with the form of chart in the 3GPP agreement.

Work as K _UEWhen≤M HSUPA UE shares identical HS-PDSCH resource, need to give each UE to distribute different training sequence deviation.For k UE, can organize at M and select m in the training sequence deviation _kThe group training sequence deviation.Then according to shared OVSF channel code and the m of HS-PDSCH resource that distributes to this UE _kEach training sequence deviation that group comprises in the training sequence deviation and the mapping relations between the OVSF channel code determine to distribute to the training sequence deviation of this UE.After assigning, K in addition _UE-1 UE can not select m again _kThe group training sequence deviation.Here, m _kOne may value be: m _k=k-1.

HS-PDSCH scheduling of resource flow process of the prior art comprises the steps: as shown in Figure 1

Step 101: base station (NODEB) is at the group number m that determines to distribute to the scheduling HS-PDSCH resource of k UE and distribute to the training sequence deviation place of this UE _kAfter, just will distribute to the information and the group number m of the scheduling HS-PDSCH resource of this UE _k(HS-SCCH) sends to k UE by the scheduling high-speed shared control channel.

Step 102: described k UE monitors scheduling HS-SCCH, and can determine to distribute to its shared OVSF channel code of scheduling HS-PDSCH according to the information of the HS-PDSCH resource of carrying on the scheduling HS-SCCH.This UE is according to the group number m that carries on this OVSF channel code and the scheduling HS-SCCH _k, inquire about m _kOrganize the mapping relations between interior training sequence deviation and the OVSF channel code, can determine to distribute to its training sequence deviation.

Scheduling HS-PDSCH resource and the training sequence deviation of step 103:NODEB by distributing to this UE sends to this UE with high speed descending sharing channel (HS-DSCH) data block of this UE.

Step 104: this UE receives NODEB by the training sequence deviation of distributing to it with scheduling HS-PDSCH resource and sends to its HS-DSCH data block.

Step 105: this UE after receiving the HS-DSCH data block that NODEB sends, if this UE to this data block correct decoding, this UE just generates and confirms (ACK) information; Otherwise this UE just generates non-affirmation (NACK) information.Simultaneously, this UE will determine channel quality indication (CQI) information of HS-PDSCH according to the signal to noise ratio (snr) of the scheduling HS-PDSCH that receives.

Step 106: this UE is by giving NODEB with the high-speed shared information channel (HS-SICH) of scheduling HS-SCCH pairing with the CQI feedback information of the ACK/NACK information of this HS-DSCH data block and up-to-date HS-PDSCH.

Step 107:NODEB can obtain the ACK/NACK information of this UE feedback and the CQI information of HS-PDSCH by the HS-SICH of decoding with scheduling HS-SCCH pairing.When NODEB receives ACK information, NODEB will no longer retransmit this data block.When NODEB receives nack message, if this HS-DSCH data block does not reach maximum number of retransmissions, NODEB will retransmit this data block; Otherwise NODEB will no longer retransmit this data block.Carry out HSDPA when scheduling at NODEB, NODEB will be according to the CQI information of the up-to-date HS-PDSCH of this UE feedback, for this UE distributes suitable scheduling HS-PDSCH resource in order to transmit the HS-DSCH data block of this UE.

MU MIMO technology only is applied to dispatch the HS-PDSCH resource among the above-mentioned HSUPA.That is: a plurality of HSUPA UE can share the resource of dispatching in the physical down shared resource pond in MU MIMO mode.Because scheduling physical down shared resource pond only accounts for a part in the downlink resource that all descending time slots constitute, therefore, MU MIMO technology is all very limited for the raising of the raising of downlink throughput capacity among the HSDPA and descending peak rate among the HSDPA at present.

In the downlink resource that all descending time slots constitute, the shared resource of downward special physical channel (DL DPCH) of distributing to each UE can not adopt MU MIMO technology.In case a part of downlink resource is distributed to certain UE as DL DPCH, this resource just can not be used for other UE.

In the downlink resource that all descending time slots constitute, the semi-static HS-PDSCH resource of distributing to each UE can not adopt MU MIMO technology equally.In a single day NODEB distributes to certain UE with certain part downlink resource as semi-static HS-PDSCH, this resource just can not be used for other UE.Unless NODEB discharges the semi-static HS-PDSCH resource of UE, distributes to the semi-static HS-PDSCH resource of UE and can be regained by NODEB.NODEB only after the semi-static HS-PDSCH resource of a UE is distributed in withdrawal, could give other UE with this resource allocation.

In the downlink resource that all descending time slots constitute, the resource that other down channels take can not adopt MU MIMO technology equally.Such as: the resource that HS-SCCH, enhancing dedicated channel absolute grant channel (E-AGCH), enhancing dedicated channel hybrid automatic repeat request indication channel (E-HICH), physical access channel (FPACH), multimedia broadcast multicast indicating channel (MICH), Secondary Common Control Physical Channel (SCCPCH) and Primary Common Control Physical Channel DSCH Downlink Shared Channels such as (PCCPCH) take just can not adopt MU MIMO technology.

In the downlink resource of free time, can not adopt MU MIMO technology equally.When having idle downlink resource (downlink resource that is not used) beyond RNC disposes to the HS-PDSCH resource pool of NODEB, this idle downlink resource is not used MU MIMO technology equally.Such as: RNC is used to support the DL DPCH of 4 SF=8 in the channel code resource of 4 SF=8 of TS6 reservation.Only dispose 1 DL DPCH in current subframe (n), taken the channel code of 1 SF=8.The channel code of all the other 3 SF=8 is temporarily vacant.In this case, the channel code resource of 3 vacant SF=8 just belongs to idle downlink resource.This idle downlink resource does not adopt MU MIMO technology equally.

If adopt MU MIMO technology in resource that other down channels beyond scheduling HS-PDSCH are shared and the idle downlink resource, just can further improve downlink throughput capacity and the descending peak rate of HSDPA.

Simultaneously, prior art only is supported in the special default training sequence deviation method of salary distribution and adopts MU MIMO technology among the HSDPA.For the HSDPA UE that does not support the special default training sequence deviation method of salary distribution, it can only determine to distribute to its training sequence deviation according to the channel code that the scheduling HS-PDSCH that distributes to it takies by the configuration mode of default training sequence deviation, and does not support the group number that will distribute to its training sequence deviation place by HS-SCCH to be notified to it.Therefore, prior art only distributes training sequence deviation to have defective based on the special default training sequence deviation method of salary distribution to UE: this mode makes the HS-PDSCH resource that the UE that do not support the special default training sequence deviation method of salary distribution can't multiplexing other UE.

If be used to distribute the downlink resource of above-mentioned down channel, in other words, can adopt MU MIMO technology if be used for the downlink resource of other down channels beyond the allocation schedule HS-PDSCH, just can will adopt the descending time slot expansion for interface quantity of MU MIMO technology to whole descending time slots.Such as: when adopting the 2:4 configuration, can expand to whole 5 descending time slots; When adopting the 3:3 configuration, can expand to whole 4 descending time slots.Like this, can effectively promote downlink throughput capacity and descending peak rate among the HSDPA.

For further improving downlink throughput capacity and the descending peak rate of HSDPA, the present invention proposes: in HSDPA, MU MIMO technology is applied to dispatch all kinds of down channels or all kinds of downlink resource outside the HS-PDSCH, makes HSDPA UE share the downlink resource that whole descending time slots constitute in MU MIMO mode.

Concrete analysis to all kinds of down channels outside the scheduling HS-PDSCH is as follows:

DL DPCH is a dedicated channel, in case distribute to a UE, is just monopolized by this UE.NODEB can know the wireless channel of the UE with DL DPCH by channel estimating.NODEB can select from all HSDPA UE and the very weak UE of wireless channel correlation with UE of DL DPCH fully, and these selecteed UE can share the shared downlink resource of DL DPCH in MU MIMO mode.

Semi-static HS-PDSCH distributes to UE by NODEB, in case NODEB distributes to UE with semi-static HS-PDSCH, this semi-static HS-PDSCH is just monopolized by this UE.Equally, NODEB can determine to have the wireless channel of the UE of semi-static HS-PDSCH by channel estimating, NODEB can select from all HSDPA UE and the very weak UE of wireless channel correlation with UE of semi-static HS-PDSCH equally, and these selecteed UE can share the shared ascending resource of semi-static HS-PDSCH in the mode of MU MIMO.

HS-SCCH is a DSCH Downlink Shared Channel.In any subframe " n ", the HSDPA scheduler of NODEB all will carry out a HSDPA scheduling.When UE of HSDPA scheduler decision scheduling, will distribute HS-SCCH and HS-PDSCH to UE.The HS-SCCH that distributes to this UE will send in the n+d1 subframe, and the HS-PDSCH that distributes to this UE will send in the n+d1+1 subframe.Here, d1 represents that NODEB carries out the time delay of HSDPA scheduling.Generally, d1=1.Therefore, in " n " subframe, the HSDPA scheduler of NODEB will distribute the resource in the descending shared resource pond of " n+d1+1 " subframe to each UE that is scheduled.In any subframe " n ", when the HSDPA scheduler of NODEB was dispatched, NODEB only knew which UE the HS-SCCH of " n+d1 " subframe belongs to, and does not know which UE the HS-SCCH of " n+d1+1 " subframe belongs to.When NODEB carries out the HSDPA scheduling in " n+1 " subframe, know just which UE the HS-SCCH of " n+d1+1 " subframe belongs to.

With respect to the HSDPA scheduling of n subframe, DSCH Downlink Shared Channels such as E-AGCH, E-HICH and FPACH have following characteristics respectively:

(1) in any subframe " n ", the HSUPA scheduler of NODEB carries out a HSUPA scheduling.When UE of HSUPA scheduler decision scheduling, will distribute E-AGCH and E-HICH to UE.The E-AGCH that distributes to this UE will send in the n+d2 subframe, and the E-HICH that distributes to this UE will send in the n+d2+2+d3 subframe.Here, d2 represents that NODEB carries out the time delay of HSUPA scheduling.D3 represents to strengthen the timing difference between the subframe that subframe that dedicated channel physical uplink channel (E-PUCH) sends and E-HICH send, and this timing difference is determined by parameter nE-HICH.Generally, d2=d1, d3=0,1,2,3.Therefore, when n subframe NODEB carried out the HSDPA scheduling, NODEB knew which UE the E-HICH of " n+d1+1 " subframe belongs to, but does not know which UE the E-AGCH of " n+d1+1 " subframe belongs to.When NODEB carries out the HSUPA scheduling in " n+1 " subframe, know just which UE the E-AGCH of n+d1+1 subframe belongs to.But, if the disposal ability of NODEB is very strong, satisfy: d2=0, during d3=0, when NODEB carries out the scheduling of " n " subframe, just may not know which UE the E-HICH of " n+d1+1 " subframe belongs to.

(2) in any subframe " n ", NODEB carries out the scheduling of a SYNC-UL sequence.When the NODEB decision responds the SYNC-UL sequence of a UE, will distribute FPACH to UE.The FPACH that distributes to this UE will send in the n+d4 subframe.If d4＞=2, then when n subframe NODEB carried out the HSDPA scheduling, NODEB knew which UE the FPACH of n+d1+1 subframe belongs to.Generally, the possible value of d4 is: 1,2,3 and 4.

In sum, when NODEB carries out HSDPA when scheduling in the n subframe, distribute the HS-PDSCH resource of " n+d1+1 " subframe to UE.NODEB may know which UE E-HICH of " n+d1+1 " subframe and FPACH belong to, and does not know which UE HS-SCCH of " n+d1+1 " subframe and E-AGCH belong to.So, belong to which UE if NODEB knows E-HICH of " n+d1+1 " subframe and FPACH, NODEB just can select appropriate H SDPA UE with MU MIMO mode sharing E-HICH and FPACH at the shared downlink resource of n+d1+1 subframe.

Based on above-mentioned analysis, the inventor proposes: HSDPA UE not only can share scheduling HS-PDSCH resource in MU MIMO mode, and can be with the downlink resource of the every other type beyond the shared scheduling of the MU MIMO mode HS-PSDCH resource.The downlink resource of these types includes but not limited to: resource that DL DPCH, semi-static HS-PDSCH, E-HICH, FPACH, HS-SCCH, E-AGCH, MICH, SCCPCH and PCCPCH are shared and idle downlink resource.

Certainly, for consideration, can not adopt MU MIMO technology in respective channel to some in other down channels or some channel quality of reception yet.Such as, can in the down channel that omnidirectional sends in the sub-district such as PCCPCH, MICH and SCCPCH, not adopt MU MIMO technology.

At this situation, the inventor proposes, and other downlink resources beyond all scheduling HS-PDSCH resources can be constituted multiple combination according to actual needs, and every kind of combination can be made of a class resource wherein, or the multiclass resource constitutes or all resource constitute.MU MIMO technological expansion can be applied in wherein any one combination.Such as: MU MIMO technology only can be extended in the idle downlink resource; Perhaps the MUMIMO technology only is extended to: in semi-persistent scheduling HS-PDSCH resource and the downlink resource of free time.

The embodiment of the invention will propose to support the HSDPA scheduler and the corresponding dispatching method of MU MIMO technology, and this scheduler and dispatching method can make the HSDPA scheduler can be with all kinds of downlink resources beyond the multiplexing scheduling of the MU MIMO mode HS-PDSCH resource.

When dispatching, distribute the scheduling HS-PDSCH resource of " n+d1+1 " subframe in any subframe " n " at the HSDPA scheduler.All kinds of down channels in " n+d1+1 " sub-frame configuration can be divided into following type:

(1) first kind channel: the HSDPA scheduler knows that when the n subframe is dispatched each down channel that belongs to the first kind in " n+d1+1 " subframe is idle or the signal of which UE of carrying.In other words, as long as scheduler knows that when the n subframe is dispatched a down channel in " n+d1+1 " subframe is idle or the signal of which UE of carrying, this down channel just belongs to the first kind.Generally, such channel includes but not limited to: semi-persistent scheduling HS-PSDCH, DL DPCH and idle downlink resource.

(2) second class channels: the HSDPA scheduler does not know that when the n subframe is dispatched at each down channel that " n+d1+1 " subframe belongs to second class be idle or the signal of which UE of carrying.In other words, as long as scheduler does not know that when the n subframe is dispatched a down channel in " n+d1+1 " subframe is idle or the signal of which UE of carrying, this down channel just belongs to second class.Generally, such channel includes but not limited to: E-AGCH and HS-SCCH.FPACH may belong to first kind channel in the scheduling of some subframe, belong to the second class channel in the scheduling of other subframe.According to above-mentioned HSUPA dispatching method, E-AGCH belongs to the second class channel certainly.But when adopting other HSUPA dispatching method, the E-AGCH channel also may become first kind channel.

(3) the 3rd class channels: the channel that omnidirectional sends includes but not limited to: PCCPCH, SCCPCH and MICH.If assurance to the quality of reception of these down channels, is not generally adopted MU MIMO technology on such channel.But, also can on these channels, adopt the MUMIMO technology in some specific application scenario.

The inventor also proposes, and adopts the default training sequence deviation method of salary distribution can support the multiplexing identical scheduling HS-PDSCH resource of a plurality of UE equally.Such as, in the default training sequence deviation method of salary distribution of descending employing, when correlation is very weak between the wireless channel of UE1 and UE2, channel code and the M1 (first training sequence deviation) of 1 SF=1 in the TS5 are distributed to UE1, with channel code in the TS5 number is 3-4, spreading factor is that channel code and the M2 of SF=16 distributes to UE2, and these two UE equally can multiplexing identical resource: the channel code that comprises two SF=16 that UE2 uses in the channel code of the SF=1 of UE1.

Embodiments of the invention one propose scheduler and the dispatching method of first kind of HSDPA.This scheduler and dispatching method not only can be realized HSDPA UE with the multiplexing scheduling of MU MIMO mode HS-PDSCH resource, and can realize the downlink resource that HSDPA UE constitutes with any one channel in multiplexing above-mentioned first kind channel of MU MIMO mode and the 3rd class channel.Here, the channel that belongs to the first kind and the 3rd class can constitute a variety of combinations, a kind of channel combination can include only a channel that belongs to the first kind, perhaps include only the channel that several belong to the first kind, perhaps comprise a channel that belongs to the 3rd class, comprise that perhaps several belong to the channel of the 3rd class, perhaps comprise the channel of one or several first kind and the channel of one or several the 3rd classes.Adopt this scheduler and dispatching method, the scheduling of each subframe is separate.This scheduler and dispatching method support simultaneously based on the special default training sequence deviation method of salary distribution and the default training sequence deviation method of salary distribution, makes the resource that the HSDPA UE that do not support the special default training sequence deviation method of salary distribution can multiplexing other UE.

Embodiments of the invention two also will propose scheduler and the dispatching method of second kind of HSDPA.This scheduler and dispatching method do not adopt resource multiplex between HSDPA UE, but support included resource in multiplexing any one channel combination that is made of the above-mentioned first kind and the 3rd class down channel of HSDPA UE.Owing to do not support the resource multiplex between the HSDPA UE, this scheduler and dispatching method and existing MU MIMO technology are irrelevant.This scheduler and dispatching method are supported the default training sequence deviation method of salary distribution, make the resource that HSUPA UE can multiplexing other down channels.

Embodiments of the invention three are used to introduce the example when not supporting multiplexed resource between the HSDPA UE and only support the multiplexing descending idling-resource of HSDPA UE, and this example can be considered as a kind of special case of embodiment two when multiplexing resource type includes only idle downlink resource.

The present invention also will provide embodiment four, and it is 1 o'clock that this embodiment is used to introduce the HS-SCCH number, support the example of multiplexing other downlink resources of HSDPA UE.It is a kind of special case of 1 o'clock at the HS-SCCH number that this example can be considered as embodiment two.

Embodiment one

Present embodiment will propose scheduler and the dispatching method of first kind of HSDPA.This scheduler and dispatching method not only can be realized HSDPA UE with the multiplexing scheduling of MU MIMO mode HS-PDSCH resource, and can realize the downlink resource that HSDPA UE constitutes with any one channel in the multiplexing above-mentioned first kind of MU MIMO mode and the 3rd class channel.Adopt this scheduler and dispatching method, the scheduling of each subframe is separate.This scheduling scheme is at first determined the combination of the HS-PDSCH channel type in addition that HSDPA UE can be multiplexing, HSDPA scheduler start-up period scheduling then.In any one subframe subsequently, the HSDPA scheduler carries out a HSDPA scheduling.

Can pre-configured application scenarios in the scheduler and the mapping table of channel type combination, in this mapping table, corresponding a kind of specific channel type combination of each application scenarios, the channel in certain every kind of channel type combination all is to belong to the above-mentioned first kind or the 3rd class channel.May be in different application scenarioss at different subframe NODEB.When the n subframe constitutes the descending shared resource of " n+d1+1 " subframe pond, scheduler is judged the scene that " n+d1+1 " subframe satisfies, inquire about described mapping table according to described application scenarios then, then can obtain the channel type combination that UE can be multiplexing, and further determine the descending shared resource pond of this subframe.The constructive method in this descending shared resource pond is more flexible.

In any subframe " n ", the scheduling flow of HSDPA scheduler comprises the steps: as shown in Figure 2

Step 201: the dispatching priority of determining each HSDPA UE of n subframe.According to dispatching priority order from high to low all UE are lined up.Come the top UE of formation and have the highest dispatching priority, come the rearmost UE of formation and have minimum dispatching priority.

The method that the scheduler of NODEB calculates each HSUPA UE dispatching priority is a lot, such as: polling method, max carrier to interference (C/I) method and equitable proportion (PF) method etc.The detailed introduction of these methods sees also existing document.Because calculating the method for the dispatching priority of each UE is not content of the present invention, repeats no more here.

Step 202: determine the HS-SCCH that can use in current subframe.In current subframe, all HS-SCCH that dispose on the carrier wave that is scheduled are available HS-SCCH.

Step 203: the descending shared resource pond of determining the n+d1+1 subframe.

Resource in the descending shared resource pond of n subframe HSDPA scheduler schedules " n+d1+1 " subframe.Therefore, need to determine: all downlink resources that will comprise in the descending shared resource pond of n+d1+1 subframe, the set of these downlink resources are exactly the descending shared resource pond of n+d1+1 subframe.

RNC disposes to the HS-PDSCH resource pool of UE and constitutes for the semi-static HS-PDSCH resource of each UE and scheduling HS-PDSCH resource by configuration.

In existing HSDPA dispatching method, MU MIMO technology can not be applied to semi-static HS-PDSCH resource, also do not comprise other resources beyond the scheduling HS-PDSCH resource, therefore the descending shared resource of " n+d1+1 " subframe pond equals to dispose the scheduling HS-PDSCH resource that forecloses and obtain to the resource that the HS-PDSCH resource pool of UE the semi-static HS-PDSCH of each UE in " n+d1+1 " subframe is taken from RNC.

The scheduler that present embodiment proposes can be realized the shared resource of various down channels that any one channel combination in multiplexing all channels combinations that are made of first kind channel and the 3rd class channel of HSDPA UE comprises, therefore, in the present embodiment, scheduler is judged the scene that " n+d1+1 " subframe satisfies, inquire about described mapping table according to described application scenarios then, then can obtain the channel type combination that UE can be multiplexing.The descending shared resource of " n+d1+1 " subframe pond comprises that all kinds of channels that comprise in the scheduling HS-PDSCH resource of above-mentioned " n+d1+1 " subframe and the combination of determined channel type are in the shared resource of " n+d1+1 " subframe.

Such as: according to above analyzing, when NODEB carried out the scheduling of n subframe, the FPACH that may know the n+d1+1 subframe was vacant or belongs to which UE, may not know that also the FPACH of n+d1+1 subframe is vacant or belongs to which UE.Therefore, can define two kinds of scenes:

First kind of scene: when NODEB carried out the scheduling of n subframe, the FPACH that knows the n+d1+1 subframe was vacant or when belonging to which UE, comprises FPACH in the channel combination.Correspondingly, the descending shared resource of n+d1+1 subframe scheduling pond comprises the resource that FPACH takies.

Second kind of scene: when NODEB carried out the scheduling of n subframe, the FPACH that does not know the n+d1+1 subframe was vacant or when belonging to which UE, does not comprise FPACH in the channel combination.Correspondingly, the descending shared resource of n+d1+1 subframe pond does not comprise the resource that FPACH takies.

Step 204: the multiplexing form in the descending shared resource of initialization pond.This step is exclusive by the present invention.

If the descending shared resource pond that step 203 is determined comprises K _TSIndividual time slot is formulated a 16 * K _TSThe multiplexing form in descending shared resource pond of dimension.J is listed as in the corresponding descending shared resource of the capable element of the i pond channel code of i SF=16 in j the time slot in this form, value z (the j of this element, i) in the expression descending shared resource pond in j time slot i channel code can (j, i) individual UE be shared in MU MIMO mode by z.Here, i represents the number of the channel code of SF=16, i=1, and 2 ..., 16; J represents j the time slot in descending shared resource pond, j=1 ..., K _TSUse t _jThe timeslot number of representing j the time slot in descending shared resource pond, and $t_1<t_2<......<t_j<......<t_{K_{\mathrm{TS}}}.$

According to the descending shared resource pond that obtains in the step 203, this 16 * K of initialization _TSThe multiplexing form in descending shared resource pond of dimension.Initial method is as follows:

For descending shared resource pond at time slot t _jThe channel code i that comprises, if this channel code is shared for other channels beyond scheduling HS-PDSCH resource and the descending idling-resource, such as, this channel code is when any one down channel takies among DLDPCH, semi-static HS-PDSCH and the E-HICH, j in the above table is listed as the i row element is initialized as Q-1, that is: z (j, i)=Q-1.This channel code is initialized as Q-1 to be represented: this channel code is used by a down channel, and this channel code is merely able to again by Q-1 UE is shared in MU MIMO mode in addition.Here, Q represents to take the maximum times that the shared resource of down channel of this channel code is re-used.Every kind of channel for comprising in the channel combination of selecting can be provided with the maximum times Q that the shared resource of this channel is re-used separately.Certainly, also the maximum times that is re-used of each channel of comprising in the channel combination can be arranged to identical Q value.

For descending shared resource pond at time slot t _jThe channel code i that comprises if this channel code is shared for scheduling HS-PDSCH resource, then is listed as j in the above table i row element and is initialized as M, that is: z (j, i)=M.Here, M represents the maximum times that each channel code of the HS-PDSCH resource occupation of this scheduling is re-used.

For descending shared resource pond at time slot t _jThe channel code i that comprises if this channel code is idle downlink resource, then is listed as the i row element with j in the above table and is initialized as P, that is: z (j, i)=P.Here, P represents the maximum times that each channel code that this idle downlink resource takies is re-used.Preferably, can make P=M.

The maximum multiplexing number P of the maximum multiplexing number Q of each channel and idle downlink resource can be identical in the combination of M and channel, also can be different.That is: scheduling HS-PDSCH resource maximum times that is re-used and the maximum multiplexing number of dispatching HS-PDSCH resource other resources in addition can be different, also can be identical.

For the descending shared resource of " n+d1+1 " subframe pond at time slot t _jChannel code i not to be covered is listed as the i row element with j in the form and is initialized as 0, that is: (j i)=0, represents that this channel code does not belong to physical down shared resource pond to z, and this channel code is unavailable.

For each time slot t _j, all carry out above-mentioned flow process, after all time slots that take when descending shared resource pond are all carried out, then finish the initialization of multiplexing form.

The value of above-mentioned parameter M, Q and P also can each subframe be arranged to different value.

Step 205: begin to dispatch UE one by one according to queue sequence from the highest UE of priority.

To the scheduling flow of a UE as shown in Figure 3, comprise the steps:

Step 205-1: when UE of scheduling, from all available HS-SCCH, select a HS-SCCH to distribute to UE.

Step 205-2: from descending shared resource pond, select a part of downlink resource to give UE as dispatching the HS-PDSCH resource allocation.

If the downlink resource of selecting can't carry the minimum data piece of UE, just finish scheduling, next UE in the formation of beginning dispatching priority to UE.To the scheduling of next UE from above-mentioned steps 205-1.

This step determines to distribute to the HS-PDSCH of UE according to following substep.

Step 205-2-1: when UE of scheduling, at first need to determine: the descending shared resource pond that this UE can use.This step is exclusive by the present invention.The method of determining the descending shared resource pond that UE can use is as follows:

1, Kong Xian downlink resource is available;

2, the down channel resources that does not carry other UE signals in the n+d1+1 subframe is available;

3, the resource that takies of the down channel that sends of omnidirectional can be used this UE.

4,, determine the signal of which UE of carrying on this down channel for the down channel that carries other UE in the n+d1+1 subframe.Correlation between the wireless channel of the UE that is carried on the wireless channel of the UE that investigation is scheduled and this down channel.If the wireless channel correlation between these two UE a little less than, just think the downlink resource that this UE that is scheduled can use this down channel to take.If the wireless channel correlation between these two UE is stronger, just think the downlink resource that this UE that is scheduled can't use this down channel to take.When UE can't use the resource that a down channel takies, resource from descending shared resource pond that this down channel is shared was removed.When the UE that is scheduled was exactly the UE that carries on this down channel, directly the resource that this down channel is shared was removed from descending shared resource pond.

If when before this UE, the UE that is successfully dispatched being arranged, need to investigate the shared downlink resource of successfully having been dispatched of UE and whether can be used by the current UE that is scheduled.Investigate the correlation of the wireless channel of the wireless channel of each UE that is successfully dispatched and the current UE of being scheduled.If the wireless channel correlation between these two UE a little less than, just think the employed downlink resource of UE that the current UE that is scheduled can use this successfully to be dispatched.If the wireless channel correlation between these two UE is stronger, just think the employed downlink resource of UE that the current UE that is scheduled can't use this successfully to be dispatched.If the current UE that is scheduled can't use one during by the employed downlink resource of the UE that successfully dispatched, the employed downlink resource of will this quilt from descending shared resource pond successfully dispatching of UE removes.

For calculating the correlation of wireless channel between two UE, need physical layer any subframe " p " with this subframe in the instantaneous value of channel estimating of any one up channel or the recursive average of channel estimating report the HSDPA scheduler.The HSDPA scheduler is known the signal of which UE of carrying on any one up channel of p subframe.Therefore, the HSDPA scheduler is known: the instantaneous value or the recursive average of channel estimating that has the UE of at least one up channel in the p subframe.When calculating the correlation between the wireless channel of two UE at the HSDPA scheduler of n subframe NODEB, use the instantaneous value or the recursive average of the channel estimating of up-to-date each UE that reports.See also pertinent literature based on wireless channel correlation calculations method between two UE of channel estimating.Because this method is not a content of the present invention, repeats no more here.

When the correlation of the wireless channel that calculates two UE, can also adopt DLBF (down beam shaping) weight vector of each UE to calculate.When adopting this method to calculate between two UE wireless channels correlation, need the DLBF weight vector of any one up channel that physical layer calculates in this subframe in any subframe (p) to report the HSDPA scheduler.Scheduler is known the signal of which UE of carrying on any one up channel of p subframe.Therefore, scheduler is known: the DLBF weight vector that has the UE of at least one up channel in the p subframe.When calculating the correlation between the wireless channel of two UE at the HSDPA scheduler of n subframe NODEB, the HSDPA scheduler uses the DLBF weight vector of up-to-date each UE that reports.See also pertinent literature based on the wireless channel correlation calculations method between two UE of DLBF weight vector.Because this method is not a content of the present invention, repeats no more here.

According to the method described above, can determine the to be scheduled available descending shared resource pond of UE.

Step 205-2-2: when not comprising any channel code in the available descending shared resource pond of the UE that is scheduled, finish scheduling, begin to dispatch next UE to this UE.To the scheduling of next UE from step 205-1.Otherwise, from the available descending shared resource pond of UE, select a part of resource to distribute to UE as HS-PDSCH.

From available descending shared resource pond, select not exceed the rectangle resource allocation of the maximum of this UE ability and give this UE.The data volume of the UE of this rectangle resource bearing can the data carried by data amount greater than other each rectangle resources in this descending shared resource pond.UE has requirement to the number of time slot of the HS-PDSCH that distributes to it, and this number of time slot can not surpass the maximum number of time slot that this UE can support.

When the rectangle resource of selecting according to the method described above can the data carried by data amount during greater than the data volume of UE, select a rectangle resource that is no more than the UE ability from available downlink resource pond, this rectangle resource is to carry minimum rectangle resource in the rectangle resource of total data amount of UE.

In this step, can also take following processing to distribute the HS-PDSCH resource to UE:

The descending shared resource pond that this is available is divided into two sub-resource pools: a sub-resource pool is made of scheduling HS-PDSCH resource in this available resources pond fully; Another child resource pond is made of the resource of other types.

Such as: RNC with whole resource distribution NODEB of TS4 as descending shared resource pond, this resource pool includes only scheduling HS-PDSCH.

RNC has disposed first type such as UL DPCH and or the up channel of the 3rd type at TS5.

When UE can with resource pool comprise: when the part resource of TS4 and the part resource of TS5, in two sub-resource pools, the resource by TS4 constitutes, and the resource by TS5 constitutes.

Distribute the rectangle resource of the maximum that is no more than the UE ability in these two sub-resource pools, for respectively this UE.The data volume of the UE that the above-mentioned rectangle resource of determining in each child resource pond can be carried can the data carried by data amount greater than other each rectangle resources in this child resource pond

If when in first child resource pond, distributing to the rectangle resource of this UE and can carry more data, just distributing to the rectangle resource of this UE in first child resource pond as the HS-PDSCH that distributes to this UE.

If when in second sub-resource pool, distributing to the rectangle resource of this UE and can carry more data, just distributing to the rectangle resource of this UE in second sub-resource pool as the HS-PDSCH that distributes to this UE.

If it is identical to distribute to the data volume of rectangle resource bearing of this UE in two sub-resource pools, select a sub-resource pool at random, will distribute to the HS-PDSCH resource of this UE in this child resource pond as the HS-PDSCH that distributes to this UE.

When the rectangle resource of selecting according to the method described above can the data carried by data amount during greater than the data volume of UE, the total data amount of selecting to carry UE from above-mentioned two sub-resource pools is no more than the rectangle resource of the minimum of UE ability again, gives UE with this rectangle resource allocation.

Step 205-3: will distribute to this UE with the HS-SICH of the HS-SCCH pairing of distributing to UE, as the scheduling HS-SICH of this UE.

Step 205-4: distribute training sequence deviation to UE.The method of salary distribution has following two kinds, adopts mode 2 to distribute training sequence deviation for this UE for the UE that does not support the special default training sequence deviation method of salary distribution.For the UE that supports the special default training sequence deviation method of salary distribution, employing mode 1 is distributed training sequence deviation to UE.

Mode 1: adopt the special default training sequence deviation method of salary distribution.All training sequence deviation in the sub-district are divided into the N group.The mapping relations of training sequence deviation and OVSF interchannel are according to 3GPP agreement TS 25.221 definition in every group.

Select one group in N group training sequence deviation, the training sequence deviation corresponding with each channel code of distributing to UE is not assigned to other UE or other down channels in this group.Give UE with this set of dispense, and the corresponding training sequence deviation of each channel code that will comprise with the HS-PDSCH that distributes to UE in will organizing is marked as " taking ".

When the maximum multiplexing number of each channel type is identical, if should be not more than 2 by the maximum multiplexing number, N=2 or N=4; If should be not more than 4, N=4 by the maximum multiplexing number.

When the maximum multiplexing number of each channel type is provided with separately, get the maximum in the maximum multiplexing number of each channel type, if this maximum is not more than 2, N=2 or N=4; If this maximum is not more than 4, N=4.

Mode 2: adopt default training sequence deviation configuration mode, the mapping relations under this mode between each training sequence deviation value and the OVSF channel code are according to 25.221 definition of TS in the 3GPP agreement.

According to the shared channel code of scheduling HS-PDSCH of distributing to this UE, look into the mapping relations between each training sequence deviation and OVSF channel code under the default training sequence deviation configuration mode, determine to distribute to the shared pairing training sequence deviation of each channel code of scheduling HS-PDSCH of UE, if part or all of training sequence has been assigned to other UE or down channel in these training sequence deviation, then the scheduling of this UE is failed: or re-execute step 205-2-2, distribute less scheduling HS-PDSCH resource for this UE; Perhaps finish scheduling, next UE in the formation of beginning dispatching priority to this UE.To the scheduling of next UE from above-mentioned steps 205-1.

Step 205-5: after according to above-mentioned steps successfully being UE distribution HS-SCCH, HS-PDSCH, HS-SICH and the training sequence deviation that is scheduled, show: this UE is successfully dispatched.The HS-SCCH that distributes to this UE is removed from available HS-SCCH; Resource updates 16 * the K shared according to the HS-PDSCH that distributes to UE _TSThe multiplexing form in descending shared resource pond of dimension; Redefine descending shared resource pond according to the multiplexing form in descending shared resource pond that upgrades.

After finishing above-mentioned processing, if do not have available HS-SCCH or descending shared resource pond not to comprise any channel code, with regard to execution in step 205-6.

After finishing above-mentioned processing, if available HS-SCCH is arranged, and descending shared resource pond comprises the channel code of 1 SF=16 at least, just begins next UE in the dispatching priority formation.To the scheduling of next UE from above-mentioned steps 205-1.

Upgrade 16 * K _TSThe method of the multiplexing form in descending shared resource pond of dimension is exclusive by the present invention, and concrete grammar is as follows:

For the HS-PDSCH that distributes to UE, if this HS-PDSCH comprises the channel code i of j time slot in the descending shared resource pond, the value that then j in the form is listed as i element subtracts one, that is: z (j, i)=z (j, i)-1.

All elements all is 0 in upgrading the later multiplexing form in descending shared resource pond, and then expression does not have available HS-PDSCH resource.Have 1 element at least greater than 0 in upgrading the later multiplexing form in descending shared resource pond, then expression has available HS-PDSCH resource, can dispatch next UE.In scheduling during next UE, descending shared resource pond is not that 0 the pairing channel code of element constitutes by upgrading in the later multiplexing form in descending shared resource pond all.

Step 205-6: each UE to successfully being dispatched sends to physical layer with distributing to HS-SCCH, the HS-PDSCH of this UE and the information of HS-SICH.

To each UE that is scheduled, physical layer at first sends to UE at the HS-SCCH that the n+d1 subframe will be distributed to this UE; In the n+d1+1 subframe HS-PDSCH is sent to UE then; At last, receive UE in the n+d1+3 subframe and send to the ACK/NACK information of HS-DSCH data block of NODEB and the CQI information of HS-PDSCH by HS-SICH.

Embodiment two

In actual applications, there is following scene:

Between HSDPA UE, do not adopt resource multiplex, but support included resource in multiplexing any one channel combination that constitutes by the above-mentioned first kind and the 3rd class down channel of HSDPA UE.

Owing to do not support the resource multiplex between the HSDPA UE, scheduler under this scene and dispatching method and existing MU MIMO technology are irrelevant.Simultaneously, scheduler under this scene and dispatching method propose the present invention other downlink resources that MU MIMO technological expansion is applied to beyond the scheduling HS-PDSCH are become: the resource that HSDPAUE can multiplexing other down channels.Here, down channel refers to first kind down channel and the 3rd class down channel.

Scheduler under above-mentioned scene and dispatching method are scheduler and the special case of dispatching method under following situation among the embodiment one.

(1) the maximum multiplexing number of scheduling HS-PDSCH resource is 1 in the descending shared resource pond;

(2) the maximum multiplexing number of idle downlink resource is 1 or greater than 1 positive integer in the descending shared resource pond;

(3) the maximum multiplexing number of the other kinds resource that comprises in the channel combination of appointment in the descending shared resource pond is 2 or greater than 2 positive integer

At the maximum multiplexing number of idle downlink resource in the above-mentioned scene be 1 and the channel appointed combination in the maximum multiplexing number of the other kinds resource that comprises be 2, the present invention proposes embodiment two.Embodiment two is from irrelevant with existing MU MIMO technology in essence.

At first, determine the combination of the channel of the other types that HSDPA UE can be multiplexing.Channel in this combination is the channel in first kind channel and the 3rd class channel.

Then, HSDPA scheduler start-up period scheduling.In any one subframe " n " subsequently, the HSDPA scheduler carries out a HSDPA scheduling.

In any subframe " n ", the scheduling flow of the HSDPA scheduler that embodiment two proposes comprises the steps: as shown in Figure 4

Step 301: the dispatching priority of determining each HSDPA UE of " n " subframe.According to dispatching priority order from high to low all UE are lined up.Come the top UE of formation and have the highest dispatching priority, come the rearmost UE of formation and have minimum dispatching priority.

Step 302: determine the HS-SCCH that can use in current subframe.In current subframe, all HS-SCCH that dispose on the carrier wave that is scheduled are available HS-SCCH.

Step 303: determine descending shared resource pond.

Resource in the descending shared resource pond of n subframe HSDPA scheduler schedules " n+d1+1 " subframe.Therefore, need to determine: all downlink resources that comprise in the descending shared resource of n+d1+1 subframe pond.

Because this scheduler can be realized the shared resource of various down channels that any one channel combination in multiplexing all channels combination that is made of first kind channel and the 3rd class channel of HSUPA UE comprises, therefore, in the present invention, the descending shared resource of " n+d1+1 " subframe pond comprises that all kinds of channels that comprise in " n+d1+1 " subframe scheduling HS-PDSCH resource and the combination of determined channel are in the shared resource of " n+d1+1 " subframe.

According to above-mentioned processing, definite channel group is share in the descending shared resource pond of determining " n+d1+1 " subframe that each subframe " n " is used.But, may be in different application scenarioss at different subframe NODEB.Can pre-defined plurality of application scenes, and be every kind of scene setting channel combination.When each subframe " n " constitutes the descending shared resource of " n+d1+1 " subframe pond, judge the scene that " n+d1+1 " subframe satisfies, adopt the channel of determining under this scene to constitute the descending shared resource pond of this subframe then.The constructive method in this scheduling physical down shared resource pond is more flexible.

Step 304: begin to dispatch UE one by one according to queue sequence from the highest UE of priority.To the scheduling flow of a UE as shown in Figure 5, comprise the steps:

Step 304-1: when UE of scheduling, from all available HS-SCCH, select a HS-SCCH to distribute to UE.

Step 304-2: from descending shared resource pond, determine the descending shared resource pond that this UE can use, from this UE can with descending shared resource pond select a part of resource to distribute to UE as HS-PDSCH.If the HS-PDSCH resource of selecting can't be carried the minimum data piece of UE, just finish scheduling, next UE in the formation of beginning dispatching priority to UE.To the scheduling of next UE from above-mentioned steps 304-1.

This step determines to distribute to the HS-PDSCH of UE according to following substep.

Step 304-2-1: when UE of scheduling, at first need to determine: the descending shared resource pond that this UE can use.This step is exclusive by the present invention.The method of determining the descending shared resource pond that UE can use is as follows:

In descending shared resource pond, determine whether to comprise in the channel combination channel type beyond the idle downlink resource, if when not comprising channel type beyond the idle downlink resource, the resource in this descending shared resource pond all is the resource that this UE can use.

If comprise the channel type beyond the idle downlink resource in the channel combination, determine the descending shared resource of " n+d1+1 " subframe pond in whether the shared resource of any one other down channel can be this UE use beyond the scheduling HS-PDSCH resource and idle downlink resource.

When this channel is a channel that omnidirectional sends when promptly belonging to the channel of the 3rd class, directly think: the resource of this channel occupancy can be used this UE.

For any one other down channel in the descending shared resource pond in " n+d1+1 " subframe, determine that this down channel is vacant or the signal of which UE of carrying.If vacant, this channel can be used this UE.Otherwise, the correlation between the wireless channel of the UE that is carried on the wireless channel of the UE that investigation is scheduled and this down channel.If the wireless channel correlation between these two UE a little less than, just think the downlink resource that this UE that is scheduled can use this down channel to take.If the wireless channel correlation between these two UE is stronger, just think the downlink resource that this UE that is scheduled can't use this down channel to take.When UE can't use the resource that a down channel takies, resource from descending shared resource pond that this down channel is shared was removed.When the UE that is scheduled was exactly the UE that carries on this down channel, directly the resource that this down channel is shared was removed from descending shared resource pond.

For calculating the correlation of wireless channel between two UE, need physical layer any subframe " p " with this subframe in the instantaneous value of channel estimating of any one up channel or the recursive average of channel estimating report the HSDPA scheduler.The HSDPA scheduler is known the signal of which UE of carrying on any one up channel of p subframe.Therefore, the HSDPA scheduler is known: the instantaneous value or the recursive average of channel estimating that has the UE of at least one up channel in the p subframe.When calculating the correlation between the wireless channel of two UE at the HSDPA scheduler of n subframe NODEB, use the instantaneous value or the recursive average of the channel estimating of up-to-date each UE that reports.See also pertinent literature based on wireless channel correlation calculations method between two UE of channel estimating.Because this method is not a content of the present invention, repeats no more here.

When the correlation of the wireless channel that calculates two UE, can also adopt DLBF (down beam shaping) weight vector of each UE to calculate.When adopting this method to calculate between two UE wireless channels correlation, need the DLBF weight vector of any one up channel that physical layer calculates in this subframe in any subframe (p) to report the HSUPA scheduler.Scheduler is known the signal of which UE of carrying on any one up channel of p subframe.Therefore, scheduler is known: the DLBF weight vector that has the UE of at least one up channel in the p subframe.When calculating the correlation between the wireless channel of two UE at the HSDPA scheduler of n subframe NODEB, the HSDPA scheduler uses the DLBF weight vector of up-to-date each UE that reports.See also pertinent literature based on the wireless channel correlation calculations method between two UE of DLBF weight vector.Because this method is not a content of the present invention, repeats no more here.

According to the method described above, can determine the to be scheduled available descending shared resource pond of UE.

Step: 304-2-2: when not comprising any channel code in the available descending shared resource pond of the UE that is scheduled, finish scheduling, begin to dispatch next UE to this UE.To the scheduling of next UE from step 304-1.Otherwise, from the available descending shared resource pond of UE, select a part of resource to distribute to UE as HS-PDSCH.

From available descending shared resource pond, select not exceed the rectangle resource allocation of the maximum of this UE Capability Requirement and give this UE.UE has requirement to the number of time slot of the HS-PDSCH that distributes to it, and this number of time slot can not surpass the maximum number of time slot that this UE can support.

When above-mentioned rectangle resource can the data carried by data amount during greater than the data volume of UE, select a rectangle resource that is no more than the UE ability from available downlink resource pond, this rectangle resource is to carry minimum rectangle resource in the rectangle resource of total data amount of UE.

In this step, can also take following processing to distribute the HS-PDSCH resource to UE:

The physical down shared resource pond that this is available is divided into two sub-resource pools: a sub-resource pool is made of scheduling HS-PDSCH resource in this available resources pond fully; Another child resource pond is made of the resource of other types.

Distribute the HS-PDSCH resource of the maximum that is no more than the UE ability in these two sub-resource pools, for respectively this UE.

If when in first child resource pond, distributing to the HS-PDSCH resource of this UE and can carry more data, just distributing to the HS-PDSCH resource of this UE in first child resource pond as the HS-PDSCH that distributes to this UE.

If when in second sub-resource pool, distributing to the HS-PDSCH resource of this UE and can carry more data, just distributing to the HS-PDSCH resource of this UE in second sub-resource pool as the HS-PDSCH that distributes to this UE.

If it is identical to distribute to the data volume of HS-PDSCH resource bearing of this UE in two sub-resource pools, select a sub-resource pool at random, will distribute to the HS-PDSCH resource of this UE in this child resource pond as the HS-PDSCH that distributes to this UE.

When the rectangle resource of selecting according to the method described above can the data carried by data amount during greater than the data volume of UE, the total data amount of selecting to carry UE from above-mentioned two sub-resource pools is no more than the rectangle resource of the minimum of UE ability again, gives UE with this rectangle resource allocation.

Step 304-3: will distribute to this UE with the HS-SICH of the HS-SCCH pairing of distributing to UE, as the scheduling HS-SICH of this UE.

Step 304-4: adopt default training sequence deviation configuration mode to distribute training sequence deviation to UE.Mapping relations under this mode between each training sequence deviation value and the OVSF channel code are according to 25.221 definition of TS in the 3GPP agreement.

Each channel code shared according to the HS-PDSCH that distributes to this UE, look into the mapping relations between each training sequence deviation and OVSF channel code under the default training sequence deviation configuration mode, determine the training sequence deviation of these channel code correspondences, these training sequence deviation are distributed to this UE.If part or all of training sequence deviation has been assigned to other UE or down channel in these training sequence deviation, then the scheduling of this UE is failed; Perhaps re-execute step 304-2-2, distribute a less HS-PDSCH resource to UE; Perhaps finish scheduling, next UE in the formation of beginning dispatching priority to this UE.To the scheduling of next UE from above-mentioned steps 304-1.

Step 304-5: after according to above-mentioned steps successfully being UE distribution HS-SCCH, HS-PDSCH, HS-SICH and the training sequence deviation that is scheduled, show: this UE is successfully dispatched.The HS-SCCH that distributes to this UE is removed from available HS-SCCH, and the resource that the HS-PDSCH that distributes to this UE is shared is removed from descending shared resource pond, the HS-SCCH and the HS-PDSCH resource that other UE can not be used distributed to this UE.After finishing above-mentioned processing, if do not have available HS-SCCH or descending shared resource pond not to comprise any channel code, with regard to execution in step 304-6.After finishing above-mentioned processing, if available HS-SCCH is arranged, and descending shared resource pond comprises the channel code of 1 SF=16 at least, just begins next UE in the dispatching priority formation.To the scheduling of next UE from above-mentioned steps 2-4-1.

Step 304-6: each UE to successfully being dispatched sends to physical layer with distributing to HS-SCCH, the HS-PDSCH of this UE and the information of HS-SICH.

To each UE that is scheduled, physical layer at first sends to UE at the HS-SCCH that the n+d1 subframe will be distributed to this UE; In the n+d1+1 subframe HS-PDSCH is sent to UE then; At last, receive UE in the n+d1+3 subframe and send to the ACK/NACK information of HS-DSCH data block of NODEB and the CQI information of HS-PDSCH by HS-SICH.

Embodiment three

Embodiment three is used to introduce the example when not supporting multiplexed resource between the HSDPA UE and only support the multiplexing descending idling-resource of HSDPA UE, and this example can be considered as the variant embodiment of embodiment two when multiplexing resource type includes only idle downlink resource.Therefore, present embodiment is from irrelevant with existing MU MIMO technology in essence.

The scheduling of HSDPA scheduler start-up period.In any one subframe " n " subsequently, the HSDPA scheduler carries out a HSDPA scheduling.

In any subframe " n ", the scheduling flow of HSDPA scheduler comprises the steps: as shown in Figure 6

Step 401: the dispatching priority of determining each HSDPA UE of " n " subframe.According to dispatching priority order from high to low all UE are lined up.Come the top UE of formation and have the highest dispatching priority, come the rearmost UE of formation and have minimum dispatching priority.

Step 402: determine the HS-SCCH that can use in current subframe.In current subframe, all HS-SCCH that dispose on the carrier wave that is scheduled are available HS-SCCH.

Step 403: determine descending shared resource pond.

Resource in the descending shared resource pond of n subframe HSDPA scheduler schedules " n+d1+1 " subframe.Therefore, need to determine: all downlink resources that comprise in the descending shared resource of n+d1+1 subframe pond.

Because this scheduler is only realized the multiplexing descending idling-resource of HSUPA UE, therefore, the descending shared resource of " n+d1+1 " subframe pond comprises the downlink resource of " n+d1+1 " subframe scheduling HS-PDSCH resource and this subframe free time.

Step 404: begin to dispatch UE one by one according to queue sequence from the highest UE of priority.To the scheduling flow of a UE as shown in Figure 7, comprise the steps:

Step 404-1: when UE of scheduling, from all available HS-SCCH, select a HS-SCCH to distribute to UE.

Step 404-2: from descending shared resource pond, select a part of resource to distribute to UE as HS-PDSCH.If the HS-PDSCH resource of selecting can't be carried the minimum data piece of UE, just finish scheduling, next UE in the formation of beginning dispatching priority to UE.To the scheduling of next UE from above-mentioned steps 404-1.

From descending shared resource pond, select not exceed the rectangle resource allocation of the maximum of this UE Capability Requirement and give this UE.UE has requirement to the number of time slot of the HS-PDSCH that distributes to it, and this number of time slot can not surpass the maximum number of time slot that this UE can support.

When above-mentioned rectangle resource can the data carried by data amount during greater than the data volume of UE, select a rectangle resource that is no more than the UE ability from available downlink resource pond, this rectangle resource is to carry minimum rectangle resource in the rectangle resource of total data amount of UE.

In this step, can also take following processing to distribute the HS-PDSCH resource to UE:

Should be divided into two sub-resource pools in descending shared resource pond: a sub-resource pool is made of scheduling HS-PDSCH resource in this available resources pond fully; Another child resource pond is made of the downlink resource of free time.

Distribute the HS-PDSCH resource of the maximum that is no more than the UE ability in these two sub-resource pools, for respectively this UE.

If when in first child resource pond, distributing to the HS-PDSCH resource of this UE and can carry more data, just distributing to the HS-PDSCH resource of this UE in first child resource pond as the HS-PDSCH that distributes to this UE.

If when in second sub-resource pool, distributing to the HS-PDSCH resource of this UE and can carry more data, just distributing to the HS-PDSCH resource of this UE in second sub-resource pool as the HS-PDSCH that distributes to this UE.

If it is identical to distribute to the data volume of HS-PDSCH resource bearing of this UE in two sub-resource pools, select a sub-resource pool at random, will distribute to the HS-PDSCH resource of this UE in this child resource pond as the HS-PDSCH that distributes to this UE.

When the rectangle resource of selecting according to the method described above can the data carried by data amount during greater than the data volume of UE, the total data amount of selecting to carry UE from above-mentioned two sub-resource pools is no more than the rectangle resource of the minimum of UE ability again, gives UE with this rectangle resource allocation.

Step 404-3: will distribute to this UE with the HS-SICH of the HS-SCCH pairing of distributing to UE, as the scheduling HS-SICH of this UE.

Step 404-4: adopt default training sequence deviation configuration mode to distribute training sequence deviation to UE.Mapping relations under this mode between each training sequence deviation value and the OVSF channel code are according to 25.221 definition of TS in the 3GPP agreement.

Each channel code shared according to the HS-PDSCH that distributes to this UE, look into the mapping relations between each training sequence deviation and OVSF channel code under the default training sequence deviation configuration mode, determine the training sequence deviation of these channel code correspondences, these training sequence deviation are distributed to this UE.

Step 404-5: after according to above-mentioned steps successfully being UE distribution HS-SCCH, HS-PDSCH, HS-SICH and the training sequence deviation that is scheduled, show: this UE is successfully dispatched.The HS-SCCH that distributes to this UE is removed from available HS-SCCH, from descending shared resource pond, remove, the HS-SCCH and the HS-PDSCH resource that other UE can not be used distributed to this UE distributing to the shared resource of the HS-PDSCH of UE.After finishing above-mentioned processing, if do not have available HS-SCCH or descending shared resource pond not to comprise any channel code, with regard to execution in step 404-6.After finishing above-mentioned processing, if available HS-SCCH is arranged, and descending shared resource pond comprises the channel code of 1 SF=16 at least, just begins next UE in the dispatching priority formation.To the scheduling of next UE from above-mentioned steps 404-1.

Step 404-6: each UE to successfully being dispatched sends to physical layer with distributing to HS-SCCH, the HS-PDSCH of this UE and the information of HS-SICH.

To each UE that is scheduled, physical layer at first sends to UE at the HS-SCCH that the n+d1 subframe will be distributed to this UE; In the n+d1+1 subframe HS-PDSCH is sent to UE then; At last, receive UE in the n+d1+3 subframe and send to the ACK/NACK information of HS-DSCH data block of NODEB and the CQI information of HS-PDSCH by HS-SICH.

Embodiment four

The embodiment four-function is 1 o'clock in introducing the HS-SCCH number, supports the example of multiplexing other downlink resources of HSDPA UE.It is 1 o'clock distortion at the HS-SCCH number that this example can be considered as embodiment two.

Basic step is at first determined the combination of the channel of the other types that HSDPA UE can be multiplexing with embodiment one, two.Channel in this combination is the channel in first kind channel and the 3rd class channel; HSDPA scheduler start-up period scheduling then.In any one subframe " n " subsequently, the HSDPA scheduler carries out a HSDPA scheduling.

In any subframe " n ", the scheduling flow of HSDPA scheduler comprises the steps: as shown in Figure 8

Step 501: the dispatching priority of determining each HSDPA UE of " n " subframe.According to dispatching priority order from high to low all UE are lined up.Come the top UE of formation and have the highest dispatching priority, come the rearmost UE of formation and have minimum dispatching priority.

Step 502: determine descending shared resource pond.

Resource in the descending shared resource pond of n subframe HSDPA scheduler schedules " n+d1+1 " subframe.Therefore, need to determine: all downlink resources that comprise in the descending shared resource of n+d1+1 subframe pond.

Because this scheduler can be realized the shared resource of each down channel that any one channel combination in multiplexing all channels combination that is made of first kind channel and the 3rd class channel of HSDPA UE comprises, therefore, in the present invention, the descending shared resource of " n+d1+1 " subframe pond comprises that all kinds of channels that comprise in " n+d1+1 " subframe scheduling HS-PDSCH resource and the combination of determined channel are in the shared resource of " n+d1+1 " subframe.

According to above-mentioned processing, definite channel group is share in the descending shared resource pond of determining " n+d1+1 " subframe that each subframe " n " is used.But, may be in different application scenarioss at different subframe NODEB.Can pre-defined plurality of application scenes, and be every kind of scene setting channel combination.When each subframe " n " constitutes the descending shared resource of " n+d1+1 " subframe pond, judge the scene that " n+d1+1 " subframe satisfies, adopt the channel of determining under this scene to constitute the descending shared resource pond of this subframe then.The constructive method in this descending shared resource pond is more flexible.

Step 503: the highest UE begins to dispatch UE from priority.To the scheduling flow of a UE as shown in Figure 9, comprise the steps:

Step 503-1: from descending shared resource pond, determine the descending shared resource pond that this UE can use, from this UE can with descending shared resource pond select a part of resource to distribute to UE as HS-PDSCH.If the HS-PDSCH resource of selecting can't be carried the minimum data piece of UE, just finish scheduling, next UE in the formation of beginning dispatching priority to UE.To the scheduling of next UE from above-mentioned steps 503-1.This step and existing method are also incomplete same.

This step determines to distribute to the HS-PDSCH of UE according to following substep.

Step 503-1-1: when UE of scheduling, at first need to determine: the descending shared resource pond that this UE can use.This step is exclusive by the present invention.The method of determining the descending shared resource pond that UE can use is as follows:

In descending shared resource pond, determine whether to comprise in the channel combination channel type beyond the idle downlink resource, if when not comprising channel type beyond the idle downlink resource, the resource in this descending shared resource pond all is the resource that this UE can use.

If comprise the channel type beyond the idle downlink resource in the channel combination, determine the descending shared resource of " n+d1+1 " subframe pond in whether the shared resource of any one other down channel can be this UE use beyond the scheduling HS-PDSCH resource and idle downlink resource.

When this channel is a channel that omnidirectional sends when promptly belonging to the channel of the 3rd class, directly think: the resource of this channel occupancy can be used this UE.

For any one other down channel in the descending shared resource pond in " n+d1+1 " subframe, determine that this down channel is idle or the signal of which UE of carrying.If idle, the resource of this channel occupancy can be used by UE.Otherwise, the correlation between the wireless channel of the UE that is carried on the wireless channel of the UE that investigation is scheduled and this down channel.If the wireless channel correlation between these two UE a little less than, just think the downlink resource that this UE that is scheduled can use this down channel to take.If the wireless channel correlation between these two UE is stronger, just think the downlink resource that this UE that is scheduled can't use this down channel to take.When UE can't use the resource that a down channel takies, resource from descending shared resource pond that this down channel is shared was removed.When the UE that is scheduled was exactly the UE that carries on this down channel, directly the resource that this down channel is shared was removed from descending shared resource pond.

For calculating the correlation of wireless channel between two UE, need physical layer any subframe " p " with this subframe in the instantaneous value of channel estimating of any one up channel or the recursive average of channel estimating report the HSDPA scheduler.The HSDPA scheduler is known the signal of which UE of carrying on any one up channel of p subframe.Therefore, the HSDPA scheduler is known: the instantaneous value or the recursive average of channel estimating that has the UE of at least one up channel in the p subframe.When calculating the correlation between the wireless channel of two UE at the HSDPA scheduler of n subframe NODEB, use the instantaneous value or the recursive average of the channel estimating of up-to-date each UE that reports.See also pertinent literature based on wireless channel correlation calculations method between two UE of channel estimating.Because this method is not a content of the present invention, repeats no more here.

When the correlation of the wireless channel that calculates two UE, can also adopt DLBF (down beam shaping) weight vector of each UE to calculate.When adopting this method to calculate between two UE wireless channels correlation, need the DLBF weight vector of any one up channel that physical layer calculates in this subframe in any subframe (p) to report the HSDPA scheduler.Scheduler is known the signal of which UE of carrying on any one up channel of p subframe.Therefore, scheduler is known: the DLBF weight vector that has the UE of at least one up channel in the p subframe.When calculating the correlation between the wireless channel of two UE at the HSDPA scheduler of n subframe NODEB, the HSDPA scheduler uses the DLBF weight vector of up-to-date each UE that reports.See also pertinent literature based on the wireless channel correlation calculations method between two UE of DLBF weight vector.Because this method is not a content of the present invention, repeats no more here.

According to the method described above, can determine the to be scheduled available descending shared resource pond of UE.

Step: 503-1-2: when not comprising any channel code in the available descending shared resource pond of the UE that is scheduled, finish scheduling, begin to dispatch next UE to this UE.To the scheduling of next UE from step 503-1.Otherwise, from the available descending shared resource pond of UE, select a part of resource to distribute to UE as HS-PDSCH.Distribution method is as follows:

From available descending shared resource pond, select not exceed the rectangle resource allocation of the maximum of this UE Capability Requirement and give this UE.UE has requirement to the number of time slot of the HS-PDSCH that distributes to it, and this number of time slot can not surpass the maximum number of time slot that this UE can support.

When above-mentioned rectangle resource can the data carried by data amount during greater than the data volume of UE, select a rectangle resource that is no more than the UE ability from available downlink resource pond, this rectangle resource is to carry minimum rectangle resource in the rectangle resource of total data amount of UE.

Step 503-2: distribute to this UE with unique HS-SCCH with the HS-SICH of this HS-SCCH pairing, as scheduling HS-SCCH and the scheduling HS-SICH of this UE.

Step 503-3: adopt default training sequence deviation configuration mode to distribute training sequence deviation to UE.Mapping relations under this mode between each training sequence deviation value and the OVSF channel code are according to 25.221 definition of TS in the 3GPP agreement.

Each channel code shared according to the HS-PDSCH that distributes to this UE, look into the mapping relations between each training sequence deviation and OVSF channel code under the default training sequence deviation configuration mode, determine the training sequence deviation of these channel code correspondences, these training sequence deviation are distributed to this UE.If part or all of training sequence deviation has been assigned to other UE or down channel in these training sequence deviation, then the scheduling of this UE is failed; Perhaps re-execute step 503-1-2, distribute a less HS-PDSCH resource to UE; Perhaps finish scheduling, next UE in the formation of beginning dispatching priority to this UE.To the scheduling of next UE from above-mentioned steps 503-1.

Step 503-4: this UE to successfully being dispatched sends to physical layer with distributing to HS-SCCH, the HS-PDSCH of this UE and the information of HS-SICH.

To this UE that is scheduled, physical layer at first sends to UE at the HS-SCCH that the n+d1 subframe will be distributed to this UE; In the n+d1+1 subframe HS-PDSCH is sent to UE then; At last, receive UE in the n+d1+3 subframe and send to the ACK/NACK information of HS-DSCH data block of NODEB and the CQI information of HS-PDSCH by HS-SICH.
